MACHINE OR DEVICE FOR CLEANING INSOLES.

Specification of Letters Patent.

Patented March 9, 1909.

Application filed A ril 12, 1am. Serial No. 367,788.

To all whom it may concern:

Be it known that I, JAMns F. NOONAN, a citizen of the United States, residing at Lynn, in the county of Essex'and Commonwealth of Massachusetts, have invented certain Improvements in Machines or Devices for Cleaning Insoles, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines or devices for cleaning insoles for boots and shoes, but more particularly for removing cement therefrom.

On account of the increased cost of leather and the necessity of turning out a low priced shoe, an insole of thin leather is now being used to which is cemented a layer of canvas or other suitable material for the purpose of In this cementing process, it is practically im ossible to prevent some of the cement or gl iie getting upon the uncovered face of the insole. When this is allowed toremain in the finished shoe, it is a great source of discomfort to the wearer, as the warmth of the foot causes it to melt and to adhere to the stocking. Heretofore, it has been necessary to employ skilled workmen and to expend a considerable amount of time in the making of this type of insole to prevent the cement getting upon the face thereof, as great difficulty was encountered in removing the same wlthout marring the surface of the leather. A siinple method of removal of this cement would make a nun torial reduction in the cost of the insole.

One feature of this invention is the use of a surface, provided with an adhesive material, to clean another surface.

Another feature consists in using a corrugated or roughened holding surface to pro vide a firm hold for this adhesive material. Preferably this holding surface is pliable or elastic.

It should be understood that the invention is not limited to any particular type of holding surface or to the cleaning of any particular article or class of articles.

One construction embodying the several features of the invention is shown in the drawings and consists in a cylinder or other suitably formed body, mounted upon a shaft rotating in journal boxes in the frame. For convenience in removing the holding surface, a sectional body may be used, of a form to be described hereinafter.

In the drawings:-Figure 1 is a perspective view of one form of the holding bod Fig. 2 is a similar view of the holding ho y detached, showing sections thereof, opened, as will be described hereinafter. Fig. 3 is a sectional view of a small portion of the cover ing of the holding body.

11 the drawings, 4. is a bed or support to lw fastened by bolts 5 to a table or other four; 7 dation, with supporting posts 6 to carry the shaft 7 seatedin the journal boxes 8. These journal boxes are held by stud bolts 9 in lugs 10 on the posts 6, so that they may easily be removed or centered. Upon the shaft 7 is placed the holding body 11, which will herc inafter be referred to as the holder. This holder may consist of a solid or otherwise constructed body, but an advantageous form fixed and a movable section, designated respectively by 12 and13. The fixed section 12 is attached to collars 14, 14 upon the shaft 7 and the movable section 13 to the fixed sec tion by the hinge 15. These sections consist of a core 16, preferably of Wood, a layer of felt 17 outside thereof, which may be ce mented to it, and a thin rubber cover 18 to be more fully described hereinafter. Rotatebly placed upon the shaft 7 are UVO'CBJIIS 19, 19, one being on each side of the holder, which may be turned into engagement with respective pins 20, 20 upon the movable sec-- tion to clasp the same to the fixed section. The collars 21, 21, movably placed. upon the shaft, are provided with set screws so that they may be rigidly fastened upon the shaft. These may be pressed against the cams 19. lgforming friction washers for the same to revent accidental rotation upon the shaft. The free edges of the sections 12 and 13 arr provided with pins 23 to grip the rubber cover, as will be described more fully hereinafter.

In Fig. 3, 514 is a small portion of an insole, showing its )osition relative to the grooves 25 of the holder 11 during the cleaning operation. 26 shows the cement between the grooves.

The form of bed or support for thrshaft i in Fig. l of the drawings.

The method of placing the cover 18 upon the holder 11 is asi follows:--0nc ed e of a is shown in Fig. 2, consisting of two parts, a

optional, but an advantageous type is shown sheet of rubber or other suitable material of proper size is pressed down upon the pins 23 on the fixedsection; the other end is carried around the holder and attached to the pins 23 on the movable section. The sections are then closed together and the cams set as described.

The method of use of this type is as follows :-A coating of cement or other adhesive material is placed upon the holding surface of the device and allowed to artially harden. The shaft is then revolved preferably in the direction of the arrow shown in Fig. 1, and an insole, held in both hands by I the operator, is wiped on the under surface of the holder in the opposite direction to the motion of that face. The adhesive material, clinging to the holding surface, removes all matter upon the surface of the insole, leaving it erfectly clean.

aving described my invention, what 1 claim as new and desire to; secune ,by Letters i Patent of the United States ism a 1. A device for removin cementl or the like from the surface of leat er, constructed for rubbin contact with the leather to be cleaned an provided upon its acting surface with a series of recesses and with hardened viscid material contained in said recesses.

2. A device for removin cement or the like from the surface of leat er, constructed for rubbing contact with the leather to be cleaned and provided with a corrugated sur face of yielding, elastic material and a layer pf adhesive material sustained upon said surace.

3. A machine for removing cement or the like from the surface of leather, comprising a movable member constructed for rubbin contact with the surface to be cleaned and provided with a roughened acting surface and with adhesive materialsustained upon said surface.

4. A machine for removing cement or the like from the surface of leather comprising a rotary member constructed for rubbing contact with the surface to be cleaned and prov-ided with a roughened acting surface of yielding material and with an adhesive sustained upon said surface.

I Ifiltestimqny whereof I have signed my fnarne tothis specification in the presence of two subscribing witnesses.
